Gamescom 2011 is in full effect. This new video for Starhawk just dropped. And when we say dropped, when mean it. Watch and you'll see. There's no mistaking the co-op here. As we've reported earlier, Starhawk features a four player online co-op mode. The more we see of this PlayStation 3 exclusive the better it looks. Check out the trailer and let us know what you think.
